If the heading didn’t give it away, I’ll insult your intelligence: I just did the Maxima/Altima (180sx) upgrade to the front of my s13. Now, can the same be done to the rears? I know that the 180sx has 240sx rears, but thats not my question. What I wan’t to know is if I can do the Maxima/Altima upgrade to the rear brakes, and if there are any problems or consequenses. And if not - WHY. Thanks guys Leo. ---

Well for starters… you wouldnt have a working e-brake 2ndly… i’m pretty sure (not 100%) but the bolt locations to mount the caliper are different from front - rear… meaning a front caliper wouldnt fit perfectly on the rear “you may have to make an adapter for it” ---

93-00 Altima SE had rear disks, so you could use those, but I think they are the same size as 240SX brakes. ---

What I really want to know is if you can put larger rotors/caipers in the rear without going -z32 / 5 lug / drilled into 4 lug- setups… 😢 ---

Well… to be honest there’s not real point, aside from maintaining the bias if you’ve upgraded your front calipers. Having good high quality rotors and pads on stock rear calipers is about as good as you really need to go. Anything oversized or with more pistons is in my oppinion overkill for the amount of work the rear brakes are ever going to encounter. If you really want to up the “performance” of your rear brakes Gas slotted and X dimpled (not drilled) rotors are the best choice. Combine that with a high end brake pad, such as EBC green stuff and you’ll be locking the rear with the hand brake and stoppingon a dime going backwards. The reason I say X dimpled is that X drilled rotors tend to overheat around the drilled holes and cause the rotor to warp, where a dimple work in a similar fassion to the gas slots. You don’t need to go crazy with the rear brakes. But you might have a squishy pedal is the bias is off from front to back. ---

There’s a bias difference between 300zx fronts and S13 rears, not 180SX fronts and 240SX rears. ---

I also have a question then. If you have the z32 upgradfe on the front wheels, do you need any upgrade on the rear to maintain a good brake bias…if so what kind of upgrade? ---

I can second that. I’ve got z32 fronts and stock rears. s14 w/ABS (slightly larger MC). Pedal feel is great. ABS works and fronts lock before rear brakes (okay bias).

Scoll down a bit and there is a economical and simple setup for the rear brakes. I tried once but did really feel like getting shit machined.

fyi…the altima/maxima setup incase u dont understand yet, is the exact same as ur current rear brakes…u can only go larger with 300zx rear brakes
